Abstract

Computer simulations have become vital in the design and configuration of manufacturing processes. Still, complex simulations have run times in the magnitude of hours to weeks. To speed up analysis processes, surrogate models are constructed, also referred to as metamodels, which can be represented as multi-dimensional functions f: R^n -> R^m. I investigate how the overall understanding of a dedicated production process can be improved by visualizing such metamodels. I created an interactive visualization approach based on Coordinated Multiple Views (CMV) that comprises different visualization techniques, all dedicated to support users in understanding different aspects of metamodels. This approach is prototypically implemented in the application memoSlice. The application aims at scaling from desktop environments to CAVE Automated Virtual Environment (CAVE) Virtual Reality (VR) systems. Thus, further research was done in interaction in VR to provide the means for a consistent interaction concept over all systems. Furthermore, various means of increasing the responsiveness of the whole system were investigated to allow for lag-free interaction in all target environments. I demonstrate the usefulness of the approaches by presenting multiple case studies.
